Title:
COMPOSITE REFRIGERANT CIRCUIT FACILITY
Document Type and Number:
Japanese Patent JP3046169
Kind Code:
B2
Abstract:
PURPOSE: To improve total refrigerating efficiency of an entire facility by moving excessive cold heat of a refrigerant circuit having a high refrigerating efficiency to a refrigerant circuit having a low refrigerating efficiency.
CONSTITUTION: Using this composite refrigerant circuit, excess refrigerating capacity of a cold storage side refrigerant circuit is stored as cold in cold accumulator of a heat storage tank 37 through a cold storage side heat storage evaporator 8 irrespective of consumption in a cold storage side evaporator 5 of a cold storage side refrigerant circuit having a high refrigerating efficiency. This cold is supplied to a refrigerating side refrigerant circuit having a low refrigerating efficiency through a refrigerating side subcooling heat exchanger 31 of the tank 37, and consumed by a refrigerating side evaporator 25 of a refrigerating side refrigerant circuit.
